3" Lift in GU9 = Traction Control and ABS Issues not experienced in GU8 wit Same Lift

[Brad_GU9]

Ok, so I can rule out the height of the G Sensor located under the front seat as the cause of the problem. Tonight I was able to rig up a temporary bracket down through a large gromet in the floor just below the factory location of the sensor. I tested the following heights from factory without any change to the vehicle behaviour.

-20mm
-50mm
-75mm
-125mm

I think now that this sensor is the one that measures the rate at which the vehicle is actually slowing compared to live braking force calculations and the VDC adds more if necessary.

So, the elusive Gravity sensor which according to the schematic diagram for my VIN is nowhere to be found, it's supposed to be under the rear seats which it is not. Sometimes they are located under the centre console, but nope it's not their either.

My other thought was that the YAW sensor could be a little over active given the increased ride height.

Can anyone help with the location of either the YAW or Gravity sensors please. Next step is to locate both of these and try lowering them by the lifted height.

Thanks
Brad
